Mr. Naidoo,
Here is the supported gbic's for the sg300 series siwtches.
They are plug and play devices and operate on a combo ports that are to the left of the gbic ports.
When you get the gbic plugged in, you can go into that ports settings and add vlans just like a regular port.
The Optical Module Status Page displays the operating conditions reported by the
SFP (Small Form-factor Pluggable) transceiver. Some information might not be
available for SFPs that do not support the digital diagnostic monitoring standard
SFF-8472.
